Give a note on balanced and unbalanced force

A balanced force exists when the net force on an object is zero. This means all forces acting on the object cancel each other out. Consequently, an object under balanced forces will either remain at rest or continue moving at a constant velocity. For example, if you push a box with 10 N of force to the right, and friction pushes back with 10 N of force to the left, the forces are balanced.

An unbalanced force exists when the net force on an object is not zero. This causes a change in the object's motion, meaning it will accelerate. Acceleration can be an increase in speed, a decrease in speed, or a change in direction. For example, if you push a box with 10 N of force to the right and friction only opposes with 5 N of force to the left, there is an unbalanced force of 5 N to the right, causing the box to accelerate in that direction.
